Tesla's Shanghai Megafactory achieves significant production landmark, manufacturing the 1,000th Megapack
In the bustling Lingang area of Pudong, Shanghai, Tesla's Shanghai Megafactory has achieved a significant milestone. The factory, which began production on February 11, 2025, has produced its 1,000th Megapack energy storage system, just under six months after the first unit rolled off the production line.
The Megapack, an ultra-large commercial energy storage battery, is Tesla's primary product at the Shanghai facility, destined for global markets. Each Megapack, resembling a shipping container and weighing over 38 tons, can store about 3,900 kWh of electricity, equivalent to the battery capacity of 62 Model 3 rear-wheel-drive vehicles.
The 1,000th Megapack will be shipped to Europe, adding to Tesla's energy products that are currently deployed in over 65 countries and regions worldwide. The energy stored in these Megapacks will significantly contribute to Tesla's global energy storage capacity, helping to maintain a reliable energy supply and prevent power outages.
The Shanghai Megafactory's annual production capacity will reach 10,000 units, with an energy storage capacity of nearly 40 GWh. This matches the output capacity of Tesla’s Lathrop Megafactory in North America, further expanding Tesla's presence in the energy storage market.
Tesla's rapid progress at the Shanghai Megafactory is evident. In Q1 2025, the factory produced over 100 Megapack batteries, signifying a strong ramp-up phase for this facility. This production rate is expected to continue, contributing to Tesla Energy’s global expansion in utility-scale battery storage systems.
To diversify its battery sourcing, Tesla has secured a major deal with LG Energy Solution to supply lithium iron phosphate (LFP) batteries for the US market from 2027 through 2030. This agreement aims to reduce reliance on Chinese suppliers and aligns with plans to open a third Megapack assembly plant near Houston, Texas in 2026.
In conclusion, Tesla's Shanghai Megafactory is playing a key role in scaling up Megapack production and exports, contributing significantly to Tesla Energy’s global expansion in utility-scale battery storage systems. The factory's success underscores Tesla's commitment to accelerating the world's transition to sustainable energy.
